This display 110 may be installed on the wall 140 by a wall mount 120 due to its thin thickness.

FIG. 3 is a perspective view illustrating a rear surface of the display shown in FIG. 1. FIG. 4 is an enlarged view of a second accommodating portion shown in FIG. 3. FIG. 5 is a perspective view from the rear of the wall mount shown in FIG. 2. FIG. 6 is an exploded perspective view illustrating the wall mount shown in FIG. 5. FIG. 7 is a perspective view illustrating a fixing bracket shown in FIG. 2. FIG. 8 is a cross-sectional perspective view taken along a line I-I′ shown in FIG. 1. FIG. 9 is an enlarged view illustrating an A portion shown in FIG. 8.

Referring to FIG. 3, the display 110 is supported by a wall mount 120 to be described later and may be fixed to the wall 140. The display 110 may include a first accommodating portion 114 formed in a rear surface 113 of the display 110.

The first accommodating portion 114 may be recessed in the rear surface 113 to accommodate both the wall mount 120 and the fixing bracket 130 to be described later. When the wall mount 120 is fixed to the fixing bracket 130, the first accommodating portion 114 may be provided in a shape corresponding to the outer shape of the wall mount 120 and the fixing bracket 130.

When the wall mount 120 is fixed to the fixing bracket 130, the first accommodating portion 114 may have a depth corresponding to the combined thicknesses of the wall mount 120 and the fixing bracket 130. Alternatively, the first accommodating portion 114 may have a minimum depth corresponding to the thickness of the fixing bracket 130 that is relatively thin and may have a maximum depth corresponding to the thickness of the wall mount 120 that is relatively thick. That is, the depth of the first accommodating portion 114 may be greater than the thickness of the fixing bracket 130 and less than the thickness of the wall mount 120.

As described above, the display 110 of the display apparatus 1 according to the example embodiment includes the first accommodating portion 114 which may accommodate both the wall mount 120 and the fixing bracket 130 on the rear surface of the display 110 so that it may be brought into close contact with the wall 140 when installed in the wall 140. Accordingly, the display apparatus according to the example embodiment can give the user an impression that the display 110 and the wall 140 are integrated with each other, and thus the appearance can be enhanced and can prevent the rear surface of the display 110 from being exposed to the outside, thereby making the appearance neat.

A wall mount coupling portion 115 to which a coupling protrusion 127 of the wall mount 120 is coupled may be provided inside the first accommodating portion 114. The wall mount coupling portion 115 may have a groove shape. The number of wall mount coupling portions 115 may be provided in accordance with the number of coupling protrusions 127. The user may fix the display 110 to the wall 140 by fixing the display 110 to the wall mount 120 so that the coupling protrusion 127 of the wall mount 120 is inserted into the wall mount coupling portion 115 provided in the first accommodating portion 114 on the rear surface 113 of the display 110. That is, the rear surface 113 of the display 110 except for a portion where the first accommodating portion 114 is formed may be in close contact with the wall 140.

The display 110 may include a first accommodating portion cover 114 a that is configured to cover the first accommodating portion 114 when the display 110 is installed on a separate support member without being installed on the wall 140. Accordingly, the display 110 according to the example embodiment is not limited in this use as a wall-mounted type, but can also be used as a stand type.

The display 110 may include a second accommodating portion 116 in which a cable C electrically connecting the display 110 and an external device is accommodated. The second accommodating portion 116 may be recessed in the rear surface 113 of the display 110. The second accommodating portion 116 may be formed to have a depth greater than the thickness of the cable C. That is, the second accommodating portion 116 may be formed to have a minimum depth corresponding to the thickness of the cable C.

Referring to FIG. 4, the second accommodating portion 116 may include a cable guide portion 117 that guides the cable C such that the cable C is drawn out of the display 110 through the bottom surface of the display 110.

The cable guide portion 117 may include a space having a shape corresponding to the shape of the cross section of the cable C and an insertion port 117 a through which the cable C may be inserted. With this configuration, the display apparatus 1 according to the example embodiment does not need to have a space for passing the cable C between the display 110 and the wall 140 so that the display 110 can be brought into close contact with the wall 140. In addition, the cable C connected to the display 110 can be easily arranged.

The display 110 may include a second accommodating portion cover 116 a that is provided to cover the second accommodating portion 116 when the cable C is not connected to the display 110 and the display 110 is not installed on the wall. Accordingly, the display 110 according to the example embodiment is not limited in this use as a wall mounted type, but may also be used as a stand type.

Referring to FIGS. 5 and 6, the wall mount 120 may be coupled to the display 110 to support the display 110 and may be fixed to the wall 140 by being coupled to a fixing bracket 130 to be described later. The wall mount 120 may include a first member 121, a tilting member 124, and a second member 126.

The first member 121 may include a shaft 122 that is releasably coupled to the fixing bracket 130. The shaft 122 may be provided to be pressable and engageable with a safety device 134 (see FIGS. 7, 9, 11 and 13) when the first member 121 is engaged with the fixing bracket 130. The shaft 122 may be provided to be rotated and press the safety device 134 so as to be detached from the fixing bracket 130 when the first member 121 is detached from the fixing bracket 130.

Specifically, referring to FIGS. 9, 11 and 13, the shaft 122 may include a fixing portion 122 a and pressing portion 122 b.

The fixing portion 122 a may be pressed by the safety device 134 after the shaft 122 is engaged with a shaft coupling portion 136 of the fixing bracket 130. Accordingly, the wall mount 120 may be firmly fixed to the fixing bracket 130 and may be prevented from being detached from the fixing bracket 130.

The pressing portion 122 b may press the safety device 134 when the shaft 122 is separated from the shaft coupling portion 136 of the fixing bracket 130. As the safety device 134 is pressed, a space for moving the shaft 122 in the direction in which the shaft 122 is separated may be formed in the shaft coupling portion 136, and thus the shaft 122 may be separated from the shaft coupling portion 136. That is, as the pressing portion 122 b presses the safety device 134, the fixing of the safety device 134 to the shaft 122 may be released.

The first member 121 may include a rotation protrusion 123 a that is rotatably coupled to a second rotating portion 128 of the second member 126. The rotation protrusion 123 a may be coupled to the second rotating portion 128 to be rotatable with respect to the second rotating portion 128 when a force greater than a predetermined magnitude is applied to the second rotating portion 128. That is, the wall mount 120 of the display apparatus 1 according to the example embodiment may be configured such that the first member 121 is rotated only when a force greater than a predetermined magnitude is applied to the second member 126 when the first member 121 is fixed to the fixing bracket 130.

The first member 121 may include a third rotating portion 123 b to which a tilting member 124 is rotatably coupled. Specifically, the third rotating portion 123 b may be rotatably coupled to a first rotating portion 125 a of the tilting member 124 by a second coupling member 152 and 153.

The tilting member 124 may include the first rotating portion 125 a rotatably coupled to the first member 121 and a guide protrusion 125 b.

The first rotating portion 125 a may be rotatably coupled to the third rotating portion 123 b of the first member 121 by the second coupling member 152 and 153, as described above.

The guide protrusion 125 b may be provided at an end portion of the tilting member 124 opposite to another end portion of the tilting member 124 provided with the first rotating portion 125 a. The guide protrusion 125 b may be slidably and/or rollably coupled to a guide slit 129 of the second member 126 which will be described later. That is, the guide slit 129 may guide the movement of the guide protrusion 125 b.

The second member 126 may include a coupling protrusion 127 coupled to the wall mount coupling portion 115 provided in the first accommodating portion 114 of the display 110. The coupling protrusion 127 may protrude from one surface of the second member 126 to which the display 110 is coupled. Although two coupling protrusions 127 are provided in the example embodiment shown in FIG. 6, the number of coupling protrusions 127 is not limited thereto. Therefore, one coupling protrusion 127 or more than two coupling protrusions 127 may be provided so that the wall mount 120 can support the display 110 firmly.

The second member 126 may include the second rotating portion 128 to which the rotation protrusion 123 a of the first member 121 is rotatably coupled. As described above, the second rotating portion 128 may be slightly fitted-coupled to allow to rotate only when a force greater than a predetermined magnitude is applied to the rotation protrusion 123 a.

The second member 126 may include the guide slit 129. The guide slit 129 may extend in the longitudinal direction of the wall mount 120 to guide the movement of the guide protrusion 125 b, as described above.

With this configuration, the wall mount 120 may be configured to be set in a close contact mode to move the display 110 in close contact with the wall 140 or a tilting mode to move the display 110 to tilt to the wall 140.

The fixing bracket 130 may be fixed to the wall 140. Referring to FIG. 7, the fixing bracket 130 may include a first bracket 131 and a second bracket 133.

The first bracket 131 may be fixed to the wall by a first fixing member 151. The first bracket 131 may include a first coupling hole 132 to which the first fixing member 151 is coupled. In addition, the first fixing member 151 may be fixed to the first coupling hole 132 in a state where a first washer 154 is coupled to the first fixing member 151.

The second bracket 133 may be fixed to the first bracket 131 by a second fixing member 155. The second bracket 133 may be fixed to the wall 140 as a third fixing member 156 is coupled to the second coupling hole 135. The second bracket 133 may include the safety device 134 and the shaft coupling portion 136. At this time, a second washer 157 may be coupled to the third fixing member 156.

The safety device 134 may have an elastic force and may be provided such that the position is changed when the shaft 122 is inserted into the shaft coupling portion 136 or separated from the shaft coupling portion 136. Specifically, the safety device 134 may be pressed by the shaft 122 when the shaft 122 is coupled to the shaft coupling portion 136 so that the safety device 134 may form a space through which the shaft 122 is inserted into the shaft coupling portion 136. The safety device 134 may be pressed by the shaft 122 when the shaft is separated from the shaft coupling portion 136 so that the safety device 134 may form a space through which the shaft 122 is separated from the shaft coupling portion 136.

The safety device 134 may be provided to press the fixing portion 122 a when the shaft 122 is inserted into the shaft coupling portion 136 and to be pressed by the pressing portion 122 b when the shaft 122 is separated from the shaft coupling portion 136. As the safety device 134 is pressed by the pressing portion 122 b, the safety device 134 becomes able to release the fixation to the shaft 122.

The shaft coupling portion 136 may be mounted on the shaft 122 to fix the wall mount 120 to the fixing bracket 130. The shaft coupling portion 136 may be provided in a shape corresponding to the shape of the shaft 122.

According to the example embodiment, with this configuration, the display apparatus can easily fix the wall mount 120 to which the display 110 is fixed to the fixing bracket 130 fixed to the wall 140 or can easily detach the wall mount 120 from the fixing bracket 130.

FIG. 10 is a cross-sectional view illustrating the display of the display apparatus shown in FIG. 1 being closely attached to the wall. FIG. 11 is an enlarged view illustrating a B portion shown in FIG. 10. FIG. 12 is a cross-sectional view illustrating a state in which the display of the display apparatus shown in FIG. 1 is tilted with respect to the wall. FIG. 13 is an enlarged view illustrating a C portion shown in FIG. 12.

Referring to FIGS. 10 and 11, when the wall mount 120 is set in the close contact mode, the wall mount 120 is positioned such that the first member 121, the second member 126, and the tilting member 124 are substantially in the same plane, and the wall mount 120 and the fixing bracket 130 are accommodated in the first accommodating portion 114. In addition, the cable C may be accommodated in the second accommodating portion 116.

At this time, the safety device 134 may press the fixing portion 122 a of the shaft 122 so that the display 110 fixed to the wall mount 120 may be securely fixed to the wall 140. Also, the coupling protrusion 127 may be inserted into the wall mount coupling portion 115.

Accordingly, the display 110 may be brought into close contact with the wall 140. Therefore, the display apparatus 1 according to the example embodiment may provide the user with an impression that the display apparatus 1 is integrated with the wall 140 and may prevent the rear surface of the display 110 from being exposed to the outside.

Referring to FIGS. 12 and 13, the wall mount 120 may be set in the tilting mode so that the display 110 may be tilted with respect to the wall 140. At this time, the guide protrusion 125 b may move within the guide slit 129 and the rotation protrusion 123 a may rotate relative to the second rotating portion 128 and the first rotating portion 125 a may rotate with respect to the third rotating portion 123 b. Accordingly, the second member 126 may be tilted with respect to the first member 121.

In addition, when the shaft 122 further rotates, the safety device 134 may be pressed by the pressing portion 122 b of the shaft 122 and form a space through which the shaft 122 may be separated from the shaft coupling portion 136. Accordingly, the wall mount 120 may be detached from the fixing bracket 130, thereby detaching the display 110 from the wall 140.
